Difference in color of laser beam from jackery's blog

How is the wavelength of each laser different?

In recent years, there are laser devices for stages that can emit various colors such as full-color lasers, but here we will briefly explain the colors of typical lasers used for blue laser pointer.

Most laser colors are red, blue, and green.


The most common colors used for laser pointers are red, green, and blue, and the red laser is probably the color that even people who are not interested in lasers have seen. The red laser pointer is a laser that is currently in the low price range because it has been mass-produced and popularized more than before. There are many purple lasers for industrial use, and they are used for DVDs, measuring instruments, printers, etc. In addition, many factories use lasers that cannot be seen in the infrared region in the high output band.

Green laser


Green lasers have also become more popular in recent years and are less expensive than they used to be. However, it seems to be more expensive than the red laser. It is generally said that red lasers are inferior to the human eye and green Burning Laser Pointers look about eight times brighter than red lasers. Even if it is said to be 8 times, it may not come out as a pin, but if you compare the same 1 mW, for example, the difference is clear.

Blue laser


Just enjoying the beautiful rays of the blue laser is one of the fascinating lasers. Blue rays are not so visible in everyday life. The light of the blue laser is very beautiful, but even if the output is about the same as the green laser, the purple laser looks overwhelmingly dark, so if you want to use a blue laser with clear brightness with emphasis on visibility You should still buy a high power laser pointer.

However, the green laser has better visibility than the blue laser, so if visibility is of the utmost importance, the green laser is recommended.
